Title: Method of constructing a hyperbolic concrete shell for a water-cooling tower
IPC: F28C1/00
Filed: 1963-12-11
Abstract: A cooling tower of hyperboloid shape is constructed by erecting above the usual grillwork base 2 of the tower a network of tensioned, spaced-apart cables 10 in two groups in which the cables cross one another, the cables being anchored at their lower ends in a ring beam 8 and at their upper ends in a tensioning device (Fig. 5, not shown), which enables the tension to be maintained and adjusted whilst the network is being embedded in a layer of a cement-like material (e.g. a cement-sand-water mix). In the form shown, vertically spaced, horizontally extending rings 28 embrace the network and are secured thereto by wires 29 (Fig. 3, not shown). The cement-like material may be applied either by blowing it through the network against a former erected inside the network, or by pouring it into shuttering erected inside and outside the network. When the cement covering reaches a point near the top of the tower the cables 10 are disconnected from the tensioning device and are bent over so that a lip may be formed (Fig. 7, not shown). The lip may extend internally and/or externally of the tower.
Patent ES-304348-A1 (ES)
Title: Improvements in or relating to elastic and bulked yarns
IPC: D02G3/32
Filed: 1964-09-24
Abstract: An elastic and bulky yarn is produced by twisting at least one twisted or untwisted strand of elastomeric filamentary material such as segmented polyurethane held under high tension e.g. sufficient to cause an extension of four times the original length, with or around at least one twisted or untwisted yarn formed of continuous, man-made e.g. polyamide or polyester, filaments and previously textured e.g. crimped in a stuffer box or by twisting or false-twisting and setting, and held under normal tension. The release of tension allows the elastomeric strand(s) to contract and increase the bulk and covering power of the textured component(s). In a woven or knitted fabric, one of the yarns may be used for each two or three other yarns, optionally formed from the same material as the textured yarn(s).

Title: Vacuum operated pump
IPC: F04B45/00
Filed: 1967-08-23
Abstract: A reciprocating gas pump comprises a compression piston 71 moving in a cylinder 51 and driven by a vacuum operated reciprocating motor having a diaphragm 17 dividing a housing 11, 12 into two chambers 18, 19 and connected to the compression piston 71 by a rod 28 passing through a bore 27 in the housing 12, the bore being provided with an O-ring seal 83 which prevents vacuum being lost from chamber 19. The motor chambers 18, 19 are alternately connected to vacuum and atmospheric pressure by a valve consisting of a member 102 oscillated on a shaft 101 by the reciprocating movement of a dummy piston 36 in a dummy cylinder 24 and connected to the diaphragm 17. An arcuate slot 103 in the member 102 connects vacuum at a port 104 alternately to ports 94, 95 leading by lines 96, 97 to respective vacuum chambers 18, 19. Gas to be compressed enters the cylinder 51, during the return stroke of the piston 71, through a filter 47, apertures 78 in a ring 44 and past an O-ring seal 76 encircling the piston 71. During the compression stroke the seal 76 prevents escape of gas from the cylinder 51, and compressed gas is discharged through an outlet valve 62.

Title: Package for storing and dispensing caustic substances
IPC: B65D81/00
Filed: 1968-02-24
Abstract: A glass bottle 2, for e.g. bromine, is encased in a shell 1, e.g. of polyethylene, and surrounded by a shock-absorbent material 3. The neck of the bottle 2 is encircled by a rigid sleeve 4, the upper part 5 of which receives, by e.g. threading, a stopper 8, which has a central part 81 which remains static when an annular part 811 is screwed home. The sleeve 4 is welded to the edge of a central aperture in a plate 6, and the outer edge of the plate 6 is welded to the shell 1. A flexible washer 7 separates the sleeve from the neck of the bottle and a sealing member 9 of disc or annular form, lies between the central stopper part 81 and the washer 7. The outer shell 1, sleeve 4, plate 6 and stopper 8 may be of the same material. To discharge the bottle contents, the stopper 8 may be replaced by a stopper having an upwardly domed central part (10), Fig. 2 (not shown), an inwardly extending pipe (11) for, e.g. the introduction of water, and an outwardly extending pipe (12) for, e.g. the discharge of aqueous bromine. The bulged part (10) and the pipes (11), (12) may be of glass or polytetrafluorethylene. The pipe (11) may be partly of flexible material to reduce fragility.

Title: Two-way plow with hydraulic trip and reset
IPC: A01B61/04
Filed: 1970-01-21
Abstract: A two-way semi-mounted plow comprises a pull tube having a rear steerable tail wheel and which journals a diagonal beam mounting two rows of opposed left and right-hand plow bottoms. Power means is provided for rotating the beam 180 DEG to alternately engage each row of bottoms with the ground. Each bottom is mounted on the end of a support arm which is pivoted to the beam. A hydraulic ram interconnects each pair of opposed support arms to extend the bottoms until the other ends of the support arms abut the beam. Upon encountering an obstacle, a bottom will deflect, compressing the ram which reacts through the opposed support arm on the frame. Thus only one ram is required for each pair of opposed bottoms.

Patent ES-394507-A1 (ES)
Title: Cutterhead and shear bar for forage harvesters
IPC: A01F29/09
Filed: 1971-08-25
Abstract: A forage harvester reel-type cutterhead having a plurality of angularly spaced knives with cutting edges on the outer periphery thereof and defining an imaginary cylindrical surface as the cutterhead rotates. The knives coact with a stationary shear bar to reduce crop material fed into the cutterhead housing by conveyor means on the harvester, the shear bar having a cutting edge generally parallel with the axis of the cutterhead and extending in close proximity to the imaginary cylindrical surface defined thereby. Each of the knives and the shear bar have a hardened, wear-resistant portion on their adjacent, substantially parallel end surfaces bordering their respective cutting edges, the hardened portions of the knives lying substantially on the imaginary cylindrical surface. During operation of the cutterhead, the softer face surfaces of the knives and shear bar wear away from the respective cutting edges to thereby maintain the sharpness of the latter. Despite such wear the clearance between the respective cutting edges of the knives and shear bar remains substantially constant during operation due to the particular configuration and relationship of the respective end surfaces of the knives and shear bar.
